BAG-SEAL.

Specification of Letters Patent.

Patented Apr. 25, 1911.

Application filed February 13, 1911. Serial No. 608,197.

To all whom it may concern;

Be it known that I, EDWARD J. BRooKs, a citizen of the United States of America, and a resident of East Orange, in the State of New Jersey, have invented a new and useful Improvement in Bag-Seals, of which the following is a specification.

This invention relates to means for securely fastening and sealing the necks of bags of textile fabric containing gold or silver coin or other valuables, or articles of merchandise, so as to insure the detection of any tampering therewith, and thus to prevent the abstraction of the contents.

The present invention consists in an im proved press-fastenable lead and cord seal for such use; and in its lead seal part as a new article of manufacture.

The leading objects of the present invention are to facilitate threading and securely fastening the cord; and to provide for tightening the cord around the neck of the bag, with the aid of the seal part and seal press, before the press-fastening operation.

Other objects will be set forth in the general description, which follows.

A sheet of drawings accompanies this specification as part thereof.

Figures 1 and 2 are respectively face and edge views of a triangular seal part of the improved construction; Fig. 3 represents a section on the line A.-B, Fig. 2; Fig. 41 is a view of the recessed edge of the sea] part; Fig. 5 is a face view of an improved bag seal embodying said triangular seal part as it leaves the factory; Fig. (3 is a like view with the seal part in section showing how the cord is threaded; Fig. 7 is an edge view of the same seal in juxtaposition to the neck of a bag and the dies of a seal press, illustrating the operation of tightening the cord; Fig. 8 is a top view of the bed die shown in Fig. 7; Fig. 9 is an edge view of the pressfastened seal; Fig. 10 is a face view of the same projected from Fig. 8; Figs. 11 and 12 are respectively an edge view and a section of a round seal part of the same functional construction as said triangular seal part; Figs. 13 and 14 are like views of a square seal part, representing another like modification of the same invention.

Like reference characters refer to like parts in all the figures.

The improved bag seal consists of a lead seal part, a or a or a of novel construction, in combination with a double-loop cord, b, adapted to embrace and secure the neck of a textile bag, 0, in customary-manner, and to be tightened and permanently fastened by the cooperation therewith of such seal part and a seal press; which latter is represented by its pair of dies, (l and e, in Figs. 7 and 8.

In each species of the invention the seal part a or a or a has three threading holes, 1, 2 and 3, preferably and conveniently parallel with each other, and a supplemental edge recess, 4; the latter crossing and communicating with all the threading holes at one edge of the seal part, as shown in Figs. 3 and 4, Fig. 6, Fig. 12 and Fig. 14, especially Fig. 1, which see. Before the seal leaves the factory, or afterward if preferred, it is threaded by inserting the cord end 1 and 2, at the recessed edge of the seal part, through the respective side holes 1 and 2, and returning them through the middle hole 3, which is of double width, so as to form two neck-embracing loops 1 and 2, Figs. 5 and 6.

In each species the seal part a or a or a is further constructed with a pair of projections, 5 and 6, on one side, at right angles to the threading holes 1, 2 and 3, and preferably and conveniently so constructed and arranged as to locate the edge recess 4 partly within that one of the projections marked 6. These projections are loosely fitted to counterpart depressions 5 and 6 in the face of one of the seal-press dies cl and 6, preferably the bed die 6, the pair of dies when the seal press is opened being so spaced apart, as represented in Fig. '7, as to only admit the seal part when said projections are within said depressions. The die depressions 5 and 6 are conveniently arranged perpendicular to the open front of the seal press. The dies d and c, or either of them, may be further provided with the customary stamping characters so as to provide the pressed seal part, represented in Figs. 9 and 10, with any desired distinguishing marks. Compare Figs. 8 and 10. Also with any desired additional projections and depressions 7 8 and 9 to effectively compress the seal part between the dies; said depressions 5' and 6 and the intermediate die portion or land 9' between them being adapted to cooperate therewith. Compare Figs. 7 and 9.

After slipping the cord loops 1 and 2 over the neck 'of the bag 0, the cord ends 1' and 2' are pulled through the seal part a or a or a to preliminarily ti hten the cord around the bag 'neck, and t e seal part s then inserted edgewise between the seal press dies at and e as represented by the arrow f, Fig. 8."In this operation the pro ections 5 and 6 and depressions 5' and 6 form alinin guides which insure the proper relation the projections, depressions and lettering of the dies to the respective portions of the seal part.

-The cord ends 1' and 2' are then pulled hard to tighten the cord b to the utmost around the bag neck; said projections 5 and 6 and die recesses 5 and 6' serving in this operation to prevent the displacement of the seal part between the'seal-press die by the pulling strain; and the cord is kept taut until the dies are closed upon the seal part as represented by the arrow h, Fig. 7, and by the product of the dies shown at a in Figs. 9 and 10. The cord ends may then be cut oil as close to the seal art .asdesired, and no knotting of the cord efore or after the sealpressing o eration is required. In the pressed sea part represented at a in Figs. 9 and 10, that portion of the cord 7) which connects the two neck-embracing loops, being inclosed within said edgerecess 4, 1s wholly inclosed within the solidified lead and protected thereby. Moreover, the returned cord ends 1' and 2 being crossed by said loop connecting portions within said recess, as in Fig. 6, both ends of each of the horseshoeshaped loops of the cordare more securely fastened within the pressed seal than heretofore. Compare Figs. 6 and 10.

, In the species represented by Figs. 1 to 10, inclusive, the seal part a is triangular in shape, with the sides of the triangle equal and its apex coincident with that end of the middle threading hole 3 which is distant fromthe edge recess 4 said recess being located within the base edge of the triangular seal part. This construction provides for a neat and secure seal part of minimum weight and cost; the savin of lead being an important consideration in the manufacture of such seals by the million.

In the species represented by Figs. 11 and 12the seal part a is round; with the middle. hole 3 diametrical, and the relation between the threading holes and projections as above described.

In the species represented by Figs. 13 and 14 the sea part a is square; the threading holes 1, 2 and 3 beingarranged parallel to two of the edges, and the recess 4 in a third edge, which makes" the latter identical with the recessed edge of the triangular seal part shown in Fig. 4.

With the dies at and e constructed or modified as above described, seal presses of ordinary make may be employed; or the.

1. An improved bag seal having, in com-- bination, a cord forming a pair of loops adapted to embrace the neck of a bag, and a compressible lead seal part having threading holes including separated side holes and a double-width middle hole, through whichlatter the returned ends of the cord protrude opposite the loops; said seal part being further constructed with an edge recess connecting said side holes and communicating with said middle hole, and adapted to inclose a loop-connecting portion of the cord crossing the returned ends within said recess.

2. An improved bag seal having, in combination, a loop-forming cord adapted to embrace the neck of a bag and a compressible lead seal part having threading holes through which the ends of the cord protrude sufiiciently to be pulled to tighten the cord around the bag neck, said seal part being further constructed with projections on one side adapted to interact with recesses in the face of one of the dies of a seal press to resist the pulling strain and prevent the displacement of the seal part between said dies.

3. An improved bag seal having, in combination, a cord forming a air of loops adapted to embrace the neck o compressible lead seal part having threading holes including separated side holes and an edge recess connecting said side holes and adapted to inclose aportion of the cord connecting the two loops, said seal part being further constructed with projections on one "side arranged at right angles to said threading holes and adapted to interact with displacement-preventing recesses in the face of one of the dies of a seal press to resist the a bag, and a pulling strain in the cord-tightening operato interact with counterpart die recesses within a seal press to prevent the displacement of the seal part by pulling strains.

5. A triangular lead seal part, for a pressfastenable bag seal, constructed With three threading holes parallel with each other adapted for threading the ends of a doubleloop cord through the seal partand returning them, the middle hole having one end at the apex of the seal part, a recess in the opposite or base edge of the seal part communicating with said holes and adapted to inclose a loop-connecting portion of the cord, and projections on one side of the seal part parallel with said recessed base edge adapted to interact with counterpart die recesses Within a seal press to prevent the displacement of the seal part by pulling strams, substantially as hereinbefore specified.
